_— “ Chapter 8 ~ =adsaf 7 Blast Damage Responsibilities A rigorous program was conducted throughout HARDTACK to insure maximum data gathering support without sacrifice of human safety. This program dealt chiefly with the radiological safety of personnel but also embodied considerations of possible damage to equipment from blast, heat and water wave action, The program included the following: 1. Dosimetry for Task Group 7.4 personnel. 2. Pre-shot planning. 3. Cloud sampling. lh. Sample return. S. Post-shot monitoring The most difficult problem in this area was the control of exposure te zediation of air and ground crews azsociated with the nuclear cloud sampling program, In the end it was necessary to obtain replacement. personnel in order not to exceed maximum permissable exposures on large muubers of propre in this program. Disimetry provided for continuous monitering cf the exposure cf each HAROTACK parvicipant te ionizing radiation through the use of . filn~badzge. The:-@ fllm-tadges were issued to all perscnnel and at a frequency dictated Gyr ~he pecson's duties. Men engaged in activites not requiring regular expcsure +o radiation were issued filn-badges at six (6) week intervals, while personnel working in hazardeus environments received Pilm-badges as citen as twise weekly, The badges were collected and read and bi-weekly tepsorts were published listing the total radiation exposures. Through this means, the radiological health of all personnel cculd be monitored and s f orten/o0e LANL RC Rl ge raaea
